It wasn't long after the GoPro Hero 2 was announced that I got on-board by including one into my arsenal of cams (thanks to Craig of Adventure Outlet for helping out on that). My only regret after having done so is that I can see so much difference in the footage quality from the previous Hero model, I am now inspired enough to replace my other cams with the new Hero 2.
Comparing footage side by side there is a marked difference in colours and fidelity, especially in low light scenarios - so much so that mixing footage from the two makes the disparity really stand out, which is why I'm now thinking of replacing all of them. While a lot of fellow kayak fishing videographers have been excited by some of it's purported new features (such as remote control, increased megapixel rating for stills) its really the Hero 2's video quality that makes it of most interest to me. Not only does it freshen up footage, it also makes for sharper screenshots, which often make for pretty good web-quality images.
It is also capable of shooting in a few new fields of view, including medium and narrow perspectives (as opposed to the standard wide setting). Unfortunately these FOV settings are only available in 1080p mode right now, but there are plans to introduce support for other resolutions in future firmware releases. Typically I shoot at 720p (to gain a frame rate advantage of 1080p) and the medium FOV will be particularly helpful when that feature is supported.
So as I prepare for my 1000km kayak fishing expedition (and the documentary I plan to shoot in the process) I am now faced with the decision to upgrade all of my GoPro cams, purely to keep the quality and fidelity of footage on a comparable level. GoPro have done a great job introducing the Hero 2... now they just have to get their act together and come good on their promises of alternative FOV shooting at different resolutions.
